As with the fella above these took almost 2 months, cant complain with the $50 Nike refund though. Was thinking Dave White 1's and the 90's samples when knocking them up.
I use those ikea type shoe trees and cover them with 2 thick wool socks then go at it. Keeps the material tight in the process also use heat on the midsoles to flatten them out at the same time, helps keep the shape.
